Abstract

The invention discloses a large-scale rearing method of siganus oramin fries. According to the large-scale rearing method of the siganus oramin fries, in a mouth opening period, fertilized eggs, at enough density, of oysters are provided for larvae which are about to open mouths in time as mouth opening bait, thus it is ensured that most of the larvae can smoothly open the mouths in the mouth opening period first time, and high-density live bait is continuously maintained in a development stage of the larvae to make all the larvae develop relatively synchronously in an early stage of fry rearing, so that individual difference of the same batch of fries is reduced as much as possible, cannibalism is reduced, the number of the fries which survive is greatly increased, the hatching rate is increased, artificial large-scale rearing of the siganus oramin fries is achieved at last, and a large number of high-quality healthy fries are provided for the siganus oramin culture industry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for large-scale cultivation of macular basket fish fry. Background technique [0002] The yellow-spotted basketfish (Siganus oramin), commonly known as Nimeng, belongs to the order Perciformes, the family Basiliformes, and the genus Siganus oramin. It is a small inshore economic fish with a wide distribution. It is distributed in the East China Sea, South China Sea and Taiwan Sea. Its meat is tender and delicious, and is deeply loved by consumers; because of its omnivorous and herbivorous feeding habits, and its preference for algae, it has the advantages of easy feed source, low breeding cost, strong disease resistance, clean netting, and feeding Short cycle and many other advantages. In recent years, the aquaculture of macular basketfish has developed rapidly, and has become one of the new objects of main and polyphagous omnivorous fish culture in offshore seawate...
